Book Cataloging Tool

Ok, I'm having way too much fun over at LibraryThing.com.
Eek what a simple, fast tool to catalog your books/library online- I love it!
Throwing books on there is a snap- and they show up automatically with pictures and links to more info- woohoo! try it- you'll see. What I've uploaded so far is under 'avaD' (go figure), if you'd like to visit my library....
A lot more to go but I am a bit sleepy.... I'll edit and add some other time.
